DOMESTIC FIREPLACE.

Application filed December 2, 1925, Serial No. 72,884, and in GreatBritain December 4, 1924.

This invention relates to domestic fireplaces, and has for its object toprovide an improved construct-ion thereof, particularly adapted forburning coke and anthracite, and

equally suitable for burning coal, wood, peat, etc, and tending to theabatement of smoke.

According to the present invention I pro vide an open fireplace whereinthe rear portion of the fuel is supported. upon a perforate grate, andthe fuel. in front for a large proportion of say to 50 of the total.fireplace area rests upon a raised plate or support beneath which an airpassage is provided opening into the rear portion of the fireplace,

the arrangemen being such that the front portion of the fire on theraised plate or support heats the air passing through the air passagebeneath and entering the fire through the rear portion of the fuel.

My invention consists of a fireplace constructed and arranged all ashereinafter more particularly described, and illustrated in theaccompanying drawing in which i Fig. 1 represents my fireplace invertical cross section, and

Fig. 2 is front elevation thereof.

Like characters of reference indicate corresponding parts in thedifferent views.

The imperforate plate I) which sup-ports the front portion of the fireand the open grate or fire bars f which supports the rear portion of thefire are arranged in substantial alignment at a suitable angle. I

The open grid or fire bars f are fitted so as to slide beneath theimperforate frontplate bso that the grate may be adjusted to suitrequirements.

The front plate 12 in this arrangement extends for substantially 25% ofthe fireplace area and beneath said plate and the grid or fire bars 7 isarranged a lower plate Z)? supported by distance pieces from theimperforate front plate I).

The improved construction can be adapted to any existing ope firqplace,or domestic stove or range, as to secure more complete con'ibustion andthe reduction oi smoke to a minimum.

If desired a complete open fire place, portable or otherwise, or a.kitchen range grate may be provided ii'icorporatii my invention, or theinvention may be applicd'to furnaces, boilers and the likewithoutnecessitating the use of force draught.

Amongst other advantages the present in vention introduces features bywhich a greatly inign'o'vcal' combus n is obtained. Frontal draught onlyis brought to hear at all depths fr in back to front of he lire. Thelire is caused to burn at two levels, al air drawn in warmed and d1 fromthe fire on the higher front. Also the loss of heat which occu s with.the usual fires supported on an open grate, due to the hot dust andashes automatically falling through the is avoided. v

hat I claim as my inventi. n and desire to secure by Letters Patent i Inan open fire1...e the combination with the fireplace side walls andhearth, of a grate including a fuel supporting rate front plate raisedabove the rear said grate ezrtendn a the width of to place to the sidewalls thereof and being po tioned. in spaced relation to the hearthwhere by an air supply passage to the rear portion of the grate isconstituted by the hearth, lircplace side 1 walls and underlie? h. face0 front portion of the grate, said pa having an unrestricted openingpermitting the air entering therethrough to impinge up the saidunderneath face of the front portion of the grate.
